I am developing brown spot on my body which happen randomly without itching, redness or pain . It varies in sizes and it develops anywhere on the body. I am suggested cosmelite next cream which is expensive and looks like have strong side effects too I wanted to know if cosmelite n glyco solves the same purpose and equally good to  help me lighten these spots.. And also if  both the cream are safe to use on sensitive places like  face , underarms , knee n elbow ?? Thank you very much
